dockershim: checkpoint HostNetwork property

To ensure kubelet doesn't attempt network teardown on HostNetwork
containers that no longer exist but are still checkpointed, make
sure we preserve the HostNetwork property in checkpoints.  If
the checkpoint indicates the container was a HostNetwork one,
don't tear down the network since that would fail anyway.

Allow log-dumping only N randomly-chosen nodes in the cluster

This should let us save "lots" (~3-4 hours) of time in our 5000-node cluster scale tests as we copy logs from all the nodes to jenkins worker and then upload all of them to gcs (while we don't need too many).
This will also prevent the jenkins container facing "No space left on device" error while dumping logs, that we saw in runs 12-13 of gce-enormous-cluster.

The longterm fix will be to enable [logexporter](https://github.com/kubernetes/test-infra/tree/master/logexporter) for our tests.

Set default User-Agent on http probe

**Set a default User-Agent on `httpGet` probes**:

Currently the default Go HTTP client sets a `User-Agent` specific to the language and version, but every Go client has the same one.  In Kubernetes, users can override the User-Agent by setting a header in their probe definition, but its tedious to do this everywhere.

This PR changes the default User-Agent only if not set (or removed) in the probe definition.

**Which issue this PR fixes** 
fixes #29025

**Special notes for your reviewer**:

**Release note**:

```release-note
Change default `httpGet` probe `User-Agent` to `kube-probe/<version major.minor>` if none specified, overriding the default Go `User-Agent`.

fixes to two pkg/util unit tests

Spun out from #46537. Trivial unit test fixes:
- `pkg/util/ebtables/ebtables_test.go`'s tests are incorrectly named and so weren't getting run by "go test". (And one of them had a typo in it so it failed after the name was fixed)
- In `pkg/util/iptables/iptables_test.go`, the deletion tests were apparently written by copying+pasting+editing the creation tests, but they forgot to change the names of the tests to match the behavior that was being tested in the new version

Allow creating special node for running heapster in GCE

This should enable scheduling heapster pod(s) in our large cluster tests, where the minions are very small (n1-standard-1) and heapster can't schedule on them due to high memory requests.

deletePod handler in the deployment controller shouldn't set owner refs

Fix Unstructured field accessor

Fix the Unstructured GetDeletionGracePeriodSeconds accessor which was
always returning nil regardless of the underlying stored value. The
field value always appearing nil prevents Custom Resource instances
from being deleted when garbage collection is enabled for CRs and
when DeletePropagationOrphan is used. More generally, this fix means that
delete-on-update now works for CR instances.

Add some test coverage for Unstructured metadata deserialization.

The Unstructured DeletionGracePeriodSeconds field marshals as a value
type from JSON and as a pointer type via SetDeletionGracePeriodSeconds.
The GetDeletionGracePeriodSeconds method now supports handling both
int64 and *int64 values so that either underlying value can be returned.

Add a reflection-based unit test which attempts to exercise all the
Object Get/Set methods for nil handling.

```release-note
Registries backed by the generic Store's `Update` implementation support delete-on-update, which allows resources to be automatically deleted during an update provided:

* Garbage collection is enabled for the Store
* The resource being updated has no finalizers
* The resource being updated has a non-nil DeletionGracePeriodSeconds equal to 0

With this fix, Custom Resource instances now also support delete-on-update behavior under the same circumstances.

kubectl: 'apply view-last-applied' must not use printf() semantics

**What this PR does / why we need it**:
This fixes `kubectl apply view-last-applied` to not use `fmt.Fprintf()`, as this will cause format codes in the YAML/JSON to be interpreted. For example, if a resource manifest contains `%r`, this would cause `view-last-applied` so print `%!r(MISSING)`.

**Special notes for your reviewer**:

Fix some flakes in autoscaler e2e on gke

This PR should fix some of the flakes we found in e2e runs, while testing for 1.7 release:
 - if one of the nodes is unschedulable in set up (causing set up to fail) we used to wait for wrong number of nodes in clean-up, adding unnecessary 20 minute wait to failing test
 - we did not check for errors when creating RC in test, leading to tests failing later in hard to debug way (added retry loop and explicit test failure)
